Abstract:

Once the user outsources the data to the big data center, he will lose the direct control on sensitive data. This lack of control poses serious challenges to the data confidentiality and integrity in the cloud storage environment. Based on the analysis of problem related to user’s data control capability weakening after outsourcing data to remote servers in the big data center, we study the problem of creating multiple copies of dynamic data file and verifying those copies stored on untrusted cloud servers and propose a map version table-based dynamic multi-copy provable data possession (MVT-DMPDP), which supports outsourcing of multi-copy dynamic data, By this way the data owner is capable of not only archiving and accessing the data copies stored by the big data center, but also updating and scaling these copies on the remote servers.

Key words: map version table (MVT), provable data possession (PDP), big data center, multi-copy, cloud server
